这是我的 配置[code=java]<?xml version="1.0" encoding="UTF-8"?>

<beans

	xmlns="http://www.springframework.org/schema/beans"

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	xmlns:p="http://www.springframework.org/schema/p"

	<!-- 拜访接口 -->

	<bean id="visitSrv" class="com.posun.webservice.system.VisitSrv"></bean>

	

</beans>

这里面总共有3个接口 ，其他2个接口没事，第3个接口测试的时候报错。
